If general call is enabled, a check must be done to determine whether the received address was a general call address (0x00).
If the received address was a general call address, then the general call must be handled by user software.
When 10-bit addressing is used to address a slave, the slave sees an interrupt following the first byte of the extended address.
User software must ensure that for this interrupt, the contents of IICD are ignored and not treated as a valid data transfer.
